The object of my invention is to provide a sheet metal sardine, can of asimple and ellieient' Construction, adapted to be rapidly and cheaplymanufactured, and to have its cover soldered on the body after the canis filled without danger of produein leaks in the soldering operation.or of snort-hing or injuring the contents of the tan. and which also maybe conveniently opened.

My invention consists in the means I employ to practically accomplishthis object or result, the same comprising certain novel constructionsof-parts and devices and novel combinations of parts and deices hereinshown and described and more partirularly specified in .theg laims.

In the accompanying drawinglorming a. part of this specification, Figurel is a pew speetive view of a sheet metal can for saw dines or otherarticles embodying my invention. Figs. 2, 3 and 4 are seetions on lines2--2. 3 3 and 4 4 respectively of Fig.1. Fig. :3 .is a plan View of thebody of the can before the cover is sean'uiwil and soldered thereto.Fig. l is an enlarged sew tion on line 6 6 of Fig. i

In the drawing. 1 represents the body of a sheet metal sardine canembodying my invention, the same being preferably .a one piece seamless,drawn body of generally reetangularshape with rounded corners 2 unit ingits upright sides 3 with its upright ends 4. The integral bottomh of thebody is preferably upwardly paneled or counter sunk, the marginal walls6 of the countersink serving to materially strengthen the body.

The can body 1 is provided at its upper end with an outstanding or rightangle seam flange 7. This seam flange 7 of the body has relatively .wideportions at the transverse and longitudinal sides of the can body andrelatively narrow portions 9 at. the four rounded corners of the canhotly. The outstanding or right angle'seam flange 'firmly clamping and 7of the ean body provided with a solder film or (eating 1t. on its uppersurface; this routing heir-r9; tusibly united to the tin (out surface olthe ("an ll()ll V flange at the factory where the run is inamllacturedand beforethe run tilled or the cover applied thereto,

lhe purpose of ll solder Coating 10 is to enable the seam tlal'ige ofthe eoi'er to be soldered or tusihly united to the seam flange of thecan body by a simple fusing operation or subjection of the. seam flangesof the (an body and cover to the neeessary heat to fuse the solder filmor coating 10.

Th cover ll Whieh is of tin plate. the same as the body of the can, isprovided will a marginal seam flange 12 to lit flat. against and in snugmetal to metal eontaet with thrsolder coated seam flange. of the can htly. The cover ll is also provided with a downwardly extendingregistering wall 13 adapted to tit snugly within the. upper end or mouthportion of the can body to reirister the cover inposition on the canboil eralily be f rmed by providing the cover with downwardly projectinghead 14 instead of by oountersinlting'the cover.

The ela-tively wide portions 8 of the seam flange 7 at the longitudinaland transverse sides of the ean body are folded over the seam flange ofthe (.(Yitl' after the (.2111 has been filled and the cover applied,thus holding the seam ilange of the (over in tight (-lose metal to metaleontaet with the SOltlQl coated seam flange 7 of the ean body. As thetold 15 of the van hotly seam flange 7 firmly embraces the seam flangeof the rotor for the greater portion of its extent, that is to say,excepting: at the rounded corners. the seam flange of the cover is veryfirmly ("lamped to the seam tlange of the body during the soldering orfusing operation, and thus enables the cover and body to be solderedtogether by perfectand hermetieally tight solder joints or seams freefrom pin holes or leaks, and this with certainty and uniformity. And asthe seam flanges of the body and cover are outstanding or outwardlyprojecting, the some may he subjeete-cl'to the necessary heat to etleotfusing of the. solder withoutdanger of seorrhing or injuring thecontents of the can.

To enable the can to he readily opened by rolling oil the cover by meansof a key in of the ean body flange does not embrace the rover flange atthe rounded corners of the can, but only at the transverse andlongitudinal side portions of the can body, the can is thus adapted tobe readily opened by rolling the cover about; a key without thenecessity of providing the cover with any scores or weakened lines. Thecover, however, may, if desired, be provided with a marginal score orweakened line extendingtroin the side edges of the key lip or tongue 16.

After the can has been filled with fish orother articles and the coverhas been applied and the outer fold portions 15 of the can body seamflange 7 folded upwardly over and around the outstanding seam flange 12ol the cover 11, thus firmly clamping the seam flanges of the body andcover together and holding the same in close metal to metal contact. therover is then soldered to the body, preferably by application ot'heat tothe outstanding seam flanges of the cover and body, thus fusing thesolder film or coating between said seam flanges and thereby forming ahermetically tight soldered seam or joint.

In practising my invention, it is preferred to provide the upper surfaceof the seam flange of the body with 'a coating of solder tusiblv unitedthereto before the can is filled as I consider this preferable either tocoating the under surface of the seam flange of the cover with thesolder or to applying molten solder to the seam flanges of the body andcover during the'soldering or heat applying operation. I11 my invention,however. the cover may be soldered to the (an body in any known orsuitable way.

As the outstanding seam flange of the can body has relatively narrowportions at the rounded corners of tljmreetangular sardine can, and asthese relatively narrow portions are not folded or clenched upward overand around the outstanding seam flange of the cover, this obviates alltendency to cramp the corners of the can, and also all tendency toseparation between theseam flanges of the body and cover at the roundedcorners. such as would be liable to result if it were at tempted to folda body flange of even width upwardly ver and around the cover flange atthe. rounded corners of the can as well as seam flanges at the roundedcorners of the can are. relatively short.

I11 my invention also, the narrowing of the seam flange of the body atthe rounded corners of the drawn can body also results in materialsaving of stock, as it materially increases the size of the scrapportions of tin plate between the corners of adjacent cans out and drawnfrom the sheet of tin plate.

I claim z 1. In a sheet metal can, the combination with a rectangularcan body having longitudinal and transverse upright sides and roundedcorners and provided at its month end with an outstanding seam flangehaving relatively wide portions at the longitudinal and transverse sidesand relatively narrow portions at the rounded corners of the can body,of a roll top sheet metal cover having an outstanding relatively narrowseam flange eorrespomling to the relatively narrow portions ot said bodyflange, the relatively wide portions of the can body flange having foldsembracing the "over flange, said cover flange having an integal tonguefoldd ed under the relatively narrow portion of the body flange at oneof the rounded corners of the can, substantially as specified.

9. In a sheet metal can, the combination with a can bodyhaving anoutstanding integral seam flange extending at substantially right anglesto the sides of the can, said flange having wide and narrow per tions,of a roll top cover provided with a tongue and having an outstandingseam flange of substantially uniform width around the entire edge, thecover'flange and narrow portion of the body flange being substantiallyof the same width and soldered together entirely around the can,

the wider portion of the body flange being bent over and around thecover flange, whereby the folded over wide portion of the body flange isadapted to firmly clamp and hold the cover and body seam flanges 120.

in close metal to metal contact and assist in preventing the same fromspringing apart, substantially as specified.

3. In a sheet metal can, the combination with a drawn, rectangular canbody hav- 12a 111g rounded corners and having an integral outstandingseam flange provided with: 'a narrow and wide portions, the narrow portion being located at one corner of the can body, of a rectangular rolltop cover haviuig 1m unfing: swam flange, being pmvid v mum (i HINT-WW pthe wide 101M01 0f the tmdy seaw 3. being: UHF Hg) and ir fhe (over fin:mm and both of sub mm width at Hm'cnrners, 05 'nm'iug wide portions i(1%umn'xnodiaiu the corners, xpuz-i xmw'lmng fuided mm and 'irx'ifl' andbody scum ml! \rumiwt and mum from spring a spcvified.
